To all whom alt may concern:

Be it known that 1', ALBERT BALL, a citizen "of the United States, and .-a resident of understood from a description or one embodiment thereof, it being understood, however, that my invention is not limited to the particular embodiment, selected for illustration.

In the drawings; Figure 1, in side elevation illustrates a machine,'made in accordance with my invention; Fig. 2, is a top view of Fig. 1; Fig. 3, is a right-hand side view of v Fig. 1; Fig. 4, details of the trunnion clamp which carries the drilling machine; and Fig.

5', details of the double quadrant and the carrier for the same.

In the machine shown in the drawings, the

' column upon which the machine is mounted is shown at A, it being provided, for in-' stance, at its lower end with suitably arranged jack screws or devices, a, for wedging the column end-wise in position, as be tween the top and bottom of a mine drift.

The coal or stone drilling machine indicated is typified at B, and may be of any suitable or desired type or construction. It is provided with'a usual. form of drill shell or cradle F, the latter having at one side a hub or arm 5, which turns in'a socket or bearing 0 formed in the saddle or collar C. The latter serves as a shell support and is in the form of a sleeve mounted to turn about a trunnion embodied in the clamp or quill D, which in turn is mounted upon the column A.

The shell-supporting saddle or collar C, is made in separable" parts, which may be clamped together, as by bolts 0, about and upon-the inclosed trunnion clamp D; and the latter in turn is. made in separable parts adapted to be'clamped by bolts, 03, upon the supporting column. Immediately below the trunnion clamp D may be placed a supporting collar E made in separable parts and provided with means, as the bolts 6, for clamping it upon the column.

The shell-supporting saddle or collar" C, (see Fig. 5} is provided with two toothed quadrants, c 0 The quadrant c meshes with the worm c on the machine carriage the handle 0 being provided for operating it. And the quadrant 0 (see Figs. 2 and 3) meshes wlth the Worm a, mounted in an arm on the trunnion clamp D, a handle 0 being provided for operating it.

Assuming the trunnion clamp D to be clamped against rotation upon the column A, it is clear that rotation of the worm 0 (Fig. 1), will cause the drilling machine to be swept about its hub 12 as a pivot through a vertical plane,'or plane parallel with the column A, for vertical or shear cutting. On the other hand if the worm c be rotated. it will cause the entire shell-supporting saddle or collar togetherwith the drilling machine to be swept horizontally about the axis of the column for horizontal or under-cutting. And in either case the worm which is not in use for sweeping the drilling machine serves as a means for maintaining fixed, or against deviation, the plane in and along which the cutting movement is taking place.

The trunnion clamp D preferably will be clamped against rotation upon the column, relying upon the worm c to produce rotative movement of the cut drilling machine about the column. Obviously, howevenwhen a. movement is desiredexceeding the possible or practicable movement by the worm 0 and its quadrant, the entire trunnion clamp may be slackened and rotated upon the column, and again clamped, if desired, in llS' new position. The shell-supporting saddle or collar, it will be seen, carries both quad rants and, with the trunnion clamp and collar E, are adjustable vertically on the col umn A to obtain the correct position of the drill or tool.

It will be noticed that the axis of the pivot or hub b is offset from the axis of the column, thus enabling inc to obtain as long a bearing for the hub as may be desired, while at the same time avoiding any material overhang V with said support and said machine for sweeping the latter in and along different planes.

' quill adjustable along said column, a saddle ity of machine adjusting devices, adjustable umn, for controlling movement of said maof the drill machine, thus giving the entire structure great stability.

Having described one embodiment of'my invention, but without limiting my invention thereto, what I claim and desire to secure by Letters Patent is 1. The combination with a rock drilling machine of a supporting column therefor, a machine carrying saddle adjustable along said columnand rotatable aboutthe same, a plurality of quadrants on said saddle anda plurality of worms therefor respectively connected with said machine and said column for sweeping the machine in and along different planes.

2. The combination with a rock drilling machine of, a support therefor, aplurality of connected quaorantsadjustable along said support and rotatable about the same, and cooperating worms respectively connected I 3. The combination with a rock drilling machine of a supporting column therefor, a

loosely surrounding said quill and'to' which said machine is pivoted, quadrants on said saddle and engaging worms mounted respectively on said machine and on said quill.

4. The combination with a rock drilling machine of a supporting column therefor, a saddle rotatable about said column and to which said machine is pivoted, the axis of said pivot and the axis of said column being ofi'se't one from the other, and means for rotating said saddle about its supporting column and for swinging said machine relative to said saddle to produce cutting actions along different planes.

5. The combination with a rock drilling machine of a support therefor and a pluralalong said support for adjusting said machine in and along different planes, said machine being controlled in one plane while undergoing adjustment in another plane...

6. The combination with a rock drilling machine of a supporting column therefor and a plurality of machine adjusting and controlling means, adjustable along said colchine in and along different intersecting planes.

7. The combination with a rock drilling machine of a supporting 'column therefor and a plurality of machine adjusting devices, adjustable along said column, and constructed respectively to sweep said machine in and along different intersecting planes, said adjusting devices being in simultaneous en ga'gement with said machine.

8. The combination with a rock drilling machine of a supporting column therefor, a collar loosely surrounding said column and adjustable along the latter, and a plurality of machine adjusting devices cooperating with said collar and constructed respectively to sweep said machine in and along different intersecting planes, said devices remaining in constant control of said machine.

9. In a rock drill, in combination, a nonrotatable supporting column; a drill cradle carried by the column and having movements circumferential and parallel with the axis thereof, and independent crank and gear mechanism for communicating each of said movements to the cradle.
